Motorbikes were a form of ground transport, typically able to carry one or two riders. They were common on Earth in the 20th and 21st centuries.

Captain Mike Yates borrowed an army motorbike to pursue Harry Mailer and his fellow inmates from Stangmoor Prison to a hangar after they captured the Thunderbolt missile. When the inmates started shooting at him, one of the tyres of the motorbike was shot and Mike came off just as it crashed straight into a pile of crates. (TV: The Mind of Evil)
Yates used a motorbike again to follow the Third Doctor and Jo Grant in Bessie when they were chased by Tom Girton in the UNIT helicopter in an attempt to drive them into Azal's heat barrier, which was surrounding Devil's End. To show Sergeant Osgood what was needed to penetrate the heat barrier, the Doctor used a felt-tipped pen to draw a circuit diagram on the motorbike's windscreen. The Doctor then used the motorbike to ride back to the village, as Yates had taken the injured Jo back to The Cloven Hoof in Bessie, but was shot at by Bert and forced to continue on foot.
